Under different circumstances, there could have been fatalities and derailment.
On February 23rd last year in Kildare, a mainline railway track experienced a total of 28 passenger trains passing over a fractured rail before the line was ultimately closed.
That's despite the issue being reported by the drivers of the initial two trains over three hours prior to the closure.
While in transit near Newbridge, a train's automatic warning system detected an issue on the rail.
The driver reported the potential fault between the Newbridge and Sallins and Naas stations at 7:11 am to a signalman.
